Definitions

  • TPEs Thermoplastic elastomers
  • Thermoplastic elastomers are polymeric materials which possess both plastic and rubbery properties. They have elastomeric mechanical properties but, unlike conventional rubbers, they can be re-processed at elevated temperatures. This re- processability is a major advantage of TPEs over chemically crosslinked rubbers since it allows recycling of fabricated parts and results in a considerable reduction of scrap.
  • Thermoplastic elastomers were prepared wherein PP resin was melted at 155°C for 2 minutes and a masterbatch of base (Table 3) or gum (Table 4) and X-LINKER 1 was mixed in for 5 minutes. CATALYST 2 was then introduced and this composition was allowed to mix until the torque value reached steady state (4 to 10 minutes) as the dispersed polydimethylsiloxane base (or gum) cured. During cure, the torque increased and the melt temperature rose to 175-185°C. As mentioned above, it is important to control the melt temperature such that the PP does not degrade (i.e., below about 200°C).
  • PBT/Silicone 30/70 30/70 40/60 40/60 60/40 60/40
  • Example 43 A series of TPSiVs based on polypropylene resin was prepared, the ingredients and proportions thereof being shown in Table 12.
  • Preparation of Example 43 is illustrative of the procedure followed: BASE 1 (140 g) was added to a Haake Model 3000 mixing bowl (300 ml) at 160°C using roller blades at 60 rpm. After 1 minute, PP 2 (60 g) was added. After mixing for about 5 minutes, the temperature had increased from 160 to about 175°C, whereupon 1.14 g of STAB were added. This was mixed for about 2 minutes and 4.8 g of CAS were added. X-LINKER 4 (4.3 g) was added about 3 minutes after the CAS.
  • the masterbatch pellets were collected and then fed back into the extruder at 2.9 kg/hr at zone 1 over element GFF2-30-90. Barrel temperatures of all zones were held at
